Question

the length of a rectangular plot is 3m more than twice its breadth.express the perimeter of the plot as a linear polynomial x

Answer 1

If the length of the plot is l
$l=3+2x$
where x is the breadth
Perimeter =$2(l+x)$
=$2(3+2x+x)$
=$2(3+3x)$
=$6(1+x)$

Answer 2

if the breadth of the rectangle is x

the length will be 3+2x

perimeter of a rectangle=2(l+b)

perimeter=2(3+2x+x)

perimeter=2(3+3x)

perimeter=6+6x
